Tutankhamun
An academic study which included DNA profiling of some of the related male mummies of the 18th Dynasty of Egypt was published in the Journal of the American Medical Association in 2010. Tutankhamun's Y-DNA haplogroup was not published in the academic paper. In 2011 iGENEA, a Swiss personal genomics company claims that King Tut belonged to Y-DNA haplogroup R1b1a2.

Ramesses III
According to a genetic study in December 2012, Ramesses III, second Pharaoh of the Twentieth Dynasty and considered to be the last great New Kingdom king to wield any substantial authority over Egypt, belonged to Y-DNA haplogroup E1b1a, mainly found in West Africa, Central Africa, Southwest Africa and Southeast Africa.

Nicholas II of Russia
Nicholas II of Russia has been predicted as having an R1b haplotype.

French Kings from Henry IV to Louis XVI "Bourbon"
King Louis XVI of France from a genetic test on blood in a cloth purported to have been collected at his beheading and maintained in an ornate gourd decorated with French Revolution themes. Confirmation of this genetic profile requires testing of a known relative. The sample was tested at two laboratories with the same results. The sample is most consistent with G2a3b1a samples.

John Adams and John Quincy Adams
United States presidents John Adams and his son John Quincy Adams belonged to Y-DNA haplogroup R1b.

Charles Darwin
Charles Darwin belonged to Haplogroup R1b, based on a sample from his great-great-grandson.

Albert Einstein
Albert Einstein belonged to haplogroup E1b1b1b2* E-Z830, with a sample taken from a paternal descendants of Naphtali Hirsch Einstein.

Genghis Khan
DNA purported to be from Genghis Khan does not have the benefit of near and easily documented lineages. A distinct 'modal' result centers today on Mongolia.
According to Zerjal et al. (2003), Genghis Khan is believed to have belonged to Haplogroup C-M130711 (xC3c-M48).

Adolf Hitler
Adolf Hitler, Chancellor of Germany from 1933 to 1945, is believed to belong to Y-DNA Haplogroup E1b1b1 (E-M35), an haplogroup which originated in East Africa about 22,400 years BP. According to Ronny Decorte, genetics expert at Katholieke Universiteit Leuven who sampled Hitler's current patrilineal living relatives, Hitler "would not have been happy" as the research could be interpreted to show that his own origins were neither "pure" nor "Aryan". Decorte said that permission from the Russian government to make a conclusive analysis of the jawbone of Adolf Hitler, or from the bloodstained cloth of the sofa where he committed suicide would put an end to the speculations, but that had not been granted.
Based on Family Tree DNA records, no less than 9% of the populations of Germany and Austria belong to the haplogroup E1b1b, and among those, the vast majority - about 80% -are not associated with Jewish ancestry. "This data clearly show that just because one person belongs to the branch of the Y-chromosome referred to as haplogroup E1b1b, that does not mean the person is likely to be of Jewish ancestry," said Professor Hammer.
Mulders confirmed the misinterpretation of his account with the following statement to Family Tree DNA: "I never wrote that Hitler was a Jew, or that he had a Jewish grandfather. I only wrote that Hitler's haplogroup is E1b1b, being more common among Berbers, Somalian people and Jews than among overall Germans. This, in order to convey that he was not exactly what during the Third Reich would have been called 'Aryan.' All the rest are speculations of journalists who didn't even take the trouble to read my article, although I had it translated into English especially for this purpose."

Napoleon Bonaparte
Napoleon belonged to haplogroup E1b1b1c1* (E-M34*). This haplogroup has its highest concentration in Ethiopia and in the Near East (Jordan). According to the authors of the study, "Probably Napoléon also knew his remote oriental patrilineal origins, because Francesco Buonaparte (the Giovanni son), who was a mercenary under the orders of the Genoa Republic in Ajaccio in 1490, was nicknamed “The Maur of Sarzane”.

Joseph Stalin
Joseph Stalin, from a genetic test on his grandson (his son Vasily's son, Alexander Burdonsky) and his grand-nephew, is shown to be Y-DNA-wise of G2a1.

The Wright Brothers
The Wright Brothers of the United States belonged to Y-DNA haplogroup E1b1b1, subclade E1b1b1a2 (V13).

Zhu Xi; the Ming Dynasty of China
Zhu Xi, the most influential Neo-Confucian scholar and philosopher in Chinese history, may have belonged to Y-DNA haplogroup O2a1a according to the DNA test of one documented descendant.

Tom Hanks
American actor Tom Hanks, a descendant of William Hanks of Richmond, Virginia, belongs to haplogroup R1a1.

Nelson Mandela
Nelson Mandela, former President of South Africa, belongs to Haplogroup E1b1a (Y-DNA) (also known as E-M2) typical of Bantu peoples.

Andrew Johnson - I2a2a (I-M223)
Andrew Johnson was the 17th President of the United States, serving from 1865 to 1869.
